Technical Field:

The utility model relates to a cable winding device, in particular to a long-distance drum type cable winding device.

Background Art:

With the rapid development of the mechanical device industry in China, large-scale mobile power supply equipment is more and more widely used. At this stage, the cable winding and unwinding equipment supporting such equipment mainly relies on import, which is not only expensive, but also can not fully meet the performance and working condition requirements of domestic equipment.

Contents:

In order to solve the shortcomings in the existing technology mentioned above, the object of the invention is to provide a long-distance drum type cable winding device for a mobile system. It can directly connect the power supply end with the mobile system. The cable will be automatically wound and unwound with the movement of the terminal. It cooperates with the worm gear deceleration system to effectively prevent the cable from breaking. It has the characteristics: easy to operate; safe and reliable; high degree of automation, etc.

In order to achieve the invention purpose mentioned above, the technology of the invention is realized in the following manner: The long-distance drum type cable winding device is mainly composed of a winding drum and a cable guider, which are connected through a sprocket and a chain. One end of the drum is provided with a slip ring box, and the other end is provided with a motor and a deceleration system. The motor adopts Y-series three-phase asynchronous motor, and the reduction system is composed of worm gear, worm, hydraulic coupler and sprocket with self-locking. The slip ring box is provided with a carbon brush, a slip ring and an insulating ring, and a pin shaft is installed between the cable guider and sprocket.

The motor is powered on to drive the worm and worm gear to rotate. The worm gear is installed on the reel shaft and can rotate freely. Two friction discs are installed on both sides of the worm gear and fixed on the reel shaft through keys. During rotation, oil film can be generated between the worm gear and them to transmit torque. Motor torque is transmitted to the reel shaft through the hydraulic coupling combined with the worm gear reduction system. The hydraulic coupler is composed of a friction disc, a compressed spring, a spring holding disc and a torque adjusting nut. The output torque can reach zero and maximum by adjusting the compression of the spring on the hydraulic clutch.

During cable retracting, the motor is powered on, and the torque output unit drives the drum to coil the cable. At this time, the hydraulic coupler slips to synchronize the cable retracting speed with the running speed of the crane.

During cable laying, the motor is powered off, and the cable traction drum rotates in the opposite direction to lay the cable. At this time, the worm gear deceleration system has self-locking performance, and the hydraulic coupler slips, so that the cable laying speed of the drum is synchronized with the running speed of the crane.

When the crane stops, the motor is powered off. At this time, the worm gear deceleration system has self-locking performance, and the hydraulic coupler can also play the role of braking, which can effectively prevent the cable from falling due to gravity.

Between the drum slip ring boxes, a group of sprockets and tapered reversing gears are led out from the reel shaft and driven by chains as the power of the cable guider. By lengthening the pin shaft of a sprocket and inserting it into the cable guider, the chain will drive the cable guider to move horizontally left and right for uniform cable laying.

When the drum retracts the cable, the cable guider arranges the cable in the forward direction. When the cable guider reaches the end point, the pin shaft on the chain rotates and reverses around the sprocket, which changes the moving direction of the cable guider and makes the cable guider arrange the cable in the reverse direction.

When the drum unwinds the cable, the cable guider arranges the cable synchronously and reversely. The cable arrangement when the cable guider reaches the end is the same as that when the cable is retracted.

Through the function of cable guider, the cables with ultra-long distance can be arranged neatly to avoid the random arrangement of cables on the drum.

Beneficial effect:

By adopting the structure mentioned above, the utility model overcomes the defect that similar foreign equipment is easy to break the cable. The design of the cable arrangement mechanism of the on-board large-scale cable drum has been optimized that hydraulic coupling deceleration system is used, which can solve the power supply problem of large-scale mobile electric equipment. The utility model has the advantages: easy and reliable operation; compact structure; saving space.
